output of up to 2,000 V. While an UltraVolt high-power C series module easily met the technical
requirements, prototyping revealed a need for both a control connector that could be secured with
screws and built-in cooling for the unit. To address these requirements, a DB15 D-sub connector

and a finned heatsink option were added to the module, and a new sample was delivered and
rapidly approved.

Additionally, the customer required a low-power, adjustable voltage DC/DC converter. In this case,
Advanced Energy engineers recommended a standard UltraVolt AA series 1/16AA24-P20 (62-V/20-W)
solution to provide a well-regulated, adjustable 0- to 62-V power supply with low ripple and good
stability.

CONCLUSION

Electroporation is an emerging therapy segment. Because of advances in precision pulsed HV
technology, we are seeing a rapid increase in terms of manufacturing inquiries on precision power
control solutions. Depending on the application, these solutions can be developed from standard
modules or configurable power supplies. However, in certain situations, a modified-standard
product or even full customization is required.

Figure 5 summarizes the various types of power technologies that can be chosen for PFA

applications. Naturally, in addition to addressing the technical specifications of a given application,
all of these technologies are compliant with the relevant medical standards to minimize the testing
and certification needed by the final system.

By choosing the best power technology for a given application, medical equipment designers can
deliver advanced ablation systems that ensure more precise targeting of tumors, improve the
efficacy of treatments and, ultimately, deliver improved outcomes for doctors and patients.
